To treat cystic fibrosis, scientists are exploring ways to use gene editing, which would correct mutations in the CFTR gene, or gene therapy, which would provide a correct copy of the CFTR gene to cells. First, they must find a way to deliver the treatment to the right cells.
mRNA therapy is one way to deliver the correct genetic instructions to cells, which would allow them to make functional CFTR protein regardless of an individual’s CF mutations.
Cystic fibrosis is caused by mutations in the gene responsible for producing the cystic fibrosis transmembrane conductance regulator (CFTR) protein. For this reason, scientists are exploring ways to provide a correct copy of the gene to treat CF.
Cystic fibrosis is caused by mutations in both copies of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. Scientists are examining whether it is possible to correct the mutations through a process called gene editing.
For gene editing and gene replacement therapies to work in cystic fibrosis, specifically engineered DNA or RNA molecules need to get inside the cells of the lung or other organs affected by CF. The process of getting these molecules into cells is referred to as gene delivery.
Stem cells are a special type of cell that can divide and produce many other cell types. Scientists are studying how adult stem cells could be used to treat cystic fibrosis.
